BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and advantages of the present invention will become more apparent from the detailed description of the embodiments of the invention. The environment in which the commodity change system 1 is used: intention. The commodity replacement system of the present invention includes a processor η, a network device, and a material device 13. The network device 12 and the processor are connected to the store through the network 6; and the storage device 13 is connected to the processor U. The storage device 13 stores the computer program 131. , database 132 and recording module 133. The computer program (3) of the storage device 13 is executed by the processor 11 of the commodity replacement system 1, and is called the product of the invention. It is only necessary to note that the product change system 1 can also be directly connected directly to the store 90 without going through the network. For example, the commodity change system 1 is installed in the quotient; g 90 cash register device (not shown), but the present invention does not 6 201039257, to this limit - and refer to the figures i to 5 The trace of the method for changing the commodity of the invention « 3 and FIG. 5 The database of the method for changing the commodity of the invention: meaning:, the diagram, FIG. 4 is the commercial commodity replacement system of the present invention as shown in FIG. 1, and the method of the present invention is used for the above-mentioned method in the plural store 9 〇 换 提供 提供 提供 提供 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿 儿The child exchange voucher includes identification;: news,; ^;; business ^90 for child exchange, such as a monthly magazine (4) or the name of the product name!

The bar code information, the biggest difference between the embodiment and the above embodiment is that the method of determining whether the offer deadline is more than the discount wear date is directly through the bar code information, and does not need to change the database 132 of the system 1 through the connected product. As shown in Figure 4, Figure 4 is a schematic illustration of a database 132 in one embodiment of the present invention. In an embodiment of the present invention, the database 132 includes child change information 1321, and the child change information 1321 includes a child exchange certificate number 1322, a product code 1323, a purchase date 1324, a discount deadline 1325, a child change date 1326, and a child change status. 1327 and children's goods 1328. It should be noted that the information included in the newsletter 1321 is not limited to the above, and the actual implementation may increase or decrease the field depending on actual needs. In an embodiment of the present invention, the child exchange certificate number 1322 refers to the number of the child purchase certificate (in the present embodiment, 201039257 12345678·1~12345678-4) '胄品玛#讯1323指指The commodity code of the product can be exchanged (in this embodiment, the product code is M〇〇〇1, for example, M〇〇〇1 refers to a monthly newsletter of a group of the same price band), and the purchase date is 1324, which refers to the purchase of the consumer. The period of the voucher exchange (in this embodiment is 98.〇413), the discount deadline is 1325, the child exchange certificate does not need to make up the difference, the child change deadline (in this embodiment, the preferential deadline is 98.08.13) The child change period 1326 is the period of the day when the consumer uses the child to change the voucher (in this embodiment, the child change date includes 98.04.14, 98.07.01 and 98.08.16) The implementation status of the certificate, the implementation of the state change 1327 will be explained later. The child 1328 is a product that the consumer 81 actually exchanges, and the store 90 can be provided for statistics. If the child does not exceed the discount wear date, then step S725 is performed: the child change job is performed. After the step S725 is completed, the state change 1327 of FIG. 4 is “already changed”. For example, if the voucher number 1322 is U3456784 and 12345678-2, the voucher is exchanged, that is, it is used within the discount deadline.
